To all whom it may concern: 1

Be it known that I, JOHN F. GODFREY, a citizen of the United States,residing at Elkhart, in the county of Elkhart and State of 5 Indiana,have invented new and useful Improv'ements in Self-Dumpin Buckets, oi?which the following isa speci cation.

My invention relates to self dumpin buckets and more especially tobuckets use for hoisting and dumping ore, coal and the like.

One object of my invention is thedproduction of aself dumping bucketprovi ed with Wheels to enable it to be elevated on an inclined guidewayor track for subsequent horizontalmovement by any suitable means H andfinally lowered and self dumped at a point substantially remote from thetop of the inclined guideway. Another obect is the production of a selfdumping ucket having a hinged dumpin bottom provided with improved latchmec anism for locking the bottom in a closed position. Other objectswill be mentioned herein from time to time and fully described.

The preferred embodiment of my invention is well illustrated in theaccompanying drawings in which Figure l'is an end elevation of a bucketembodying my invention;

so Fig. 2 is a side elevation of the bucket; Fig.

3 is a: top (plan view; Fig. 4 is a bottom plan view; an Fig. 5 is afragment showing the carrier and latch mechanism for the dumping bottom.

Similar numerals of reference refer to similar members and parts ofmembers throughout the several-views on thedrawin Y eferring to thedrawings in detail, the numeral 1 indicates a bucketbody formed of anysuitable. material and open-at its 'top for loading, provided with ahinged dumping bottom,- as will be hereinafter described, for discharginthe" bucket load. A bail 2 is attached to t 1e bucket 1 to which ahoisting cable ma be connected in any suitable manner, sai bail being"pivotally carried upon the wheel axles 3, 3 which are rigidly mountedupon the bucket body and vu iupn porting the outboard end of the wheel I66 axles 3.

manner.

members mounted upon the bucket body at 7, 7, and adapted to beretracted by the springs 8, 8 after the discharge of the bucket load,said springsbeing attached to the bottomand bucket at 9 and 10,respectively. The bottom 6 is provided also with achanneled retainer bar11 extending across the under side thereof and to which it is rigidlyfastened in any suitable manner such as bolts or rivets, one end ofwhich bar projects somewhat beyond the edge of the bot tom 6.The'numeral 12 indicates a shoulder carried by the bar 11 and adapted toserve as an abutment member, or portion, for the latch hereinafterdescribed.

-The-numeral 13 indicates a latch hook pivotally mounted at 14: upon thebucket' bottom carrier member 15, the latter being pivotally supportedupon the pin 16 which is carried in the pin brackets 17 l7 rigidlyfastened to the bucket body in any suitable The numeral 18 indicates asup porting ledge provided on the member 15 and upon which the end ofthe retainer bar 11 rests and upon which it is normally con fined by theengagement of the latch book 13 with the retainer bar shoulder 12. Thecarrier 15 is provided with the extension 19 upon. the lower end ofwhich is provided a pair of laterally projecting arms 20, 20, one ofsaid arms being suitably apertured at 21 to receive and guide the latchactuation rod 22, the latter being pivotally fastened to the latch hook13 by a pin 23. The latch actuation rod 22' is provided with a. knob 24at its lower extremity, said knob, being nor-- it until the knob 24strikes the floor, or surface of the depository, thereby raising thelatch hook 13 and unlatching theretainer bar, and thereby the bottom 6,whereby the carrier member 15 is free to be swung on its pivot 16 todisengage. the ledge 18 fron thecnd of the retainer bar 11, suchdisengagement being effected by the c'ontact of the carrier-arms 20, 20with the depository floor,

orits contents, assisted by the weight of the bucket load, while thebucket 1 is swin ing' naturally back and forth at the'end 0 its hoistingcable.

' thereupon engaging beneath the end of the 4 is displaced onl bar 11 onthe return swing of said carrier member and the shoulder 12 is engagedby the hook latch 13, whereby pivotal. movement of the carrier 15 isprevented and thereby locking the ledge 18 beneath the end of the bar11. Norma ly the weight of the carrier arm 19 and the arms 20, 20 servesas a counter balance to swing the carrier member 15 into a perpendicularposition, thereb ositioning the ledge 18 directly beneat t e end of theretainer bar 11, following the upward swing of the bottom 6, for anporting said bottom when the bucket is loariiad. And when said'carrier15 swings itself into a substantially perpendicular sition the latchhook '13 1s lifted and pped into engagement with the shoulder 12 .of thebar 11 from which engagement it by the u ward movement of the latch ro22 when ifted by the engagement of the knob 2-1 with a stop memher whenthe bucket is lowered, as described.

'While In primarily or handling and a moving coal nevertheless it may beused for handling and transferring any divided .or disintegratedmaterials.

I claim:

1. The combination with a bucketprovided with a hinged dumping door, ofa dumping door carrier pivotally carried by the bucket, said carrierbeing provided with a ledge adapted to support said door and to be movedinto and out of supporting relation therewith when said door carrier isswung upon its pivot; a movable latch hook carried by said door carrierand detachably locking said carrier ledge in supporting relation with'said dumping door; and .latch hook disengaging means actuated when thebucket descends whereby said door carrier ledge is freed for movementout of supporting relation with said dumping door.

2, The combination witha bucket provided with a'hinged dumping door, ofa dumpin door carrier movably carried by said buc et, said' carrierbeing provided with a ledge adapted to support said door and to be movedintoand out of supportingrelation therewith when said door carrier isactuated; a movable latch hook supported by.

said door carrieriand detachably locking said carrier ledge insupporting relation withsaid dumping door; a latch actuation memberoperatively connected with said latch hook and adapted-to actuate saidlatch hook when the bucket descends whereby said door carrier ledge isfreed for movethe unlatched bottom 6, as de improved bucket is intendeddetachably engaging the shoulder on said shouldered member whereby saidcarrier and carrier ledge are detachably. locked in supporting relationwith said dumping door,

shouldered member; and latch hook disengaging means actuated when thebucket descends, whereby said door carrier ledge is freed for movementout of supportin relation with said dumping door shou dered member.

4. The combination with a bucket PM vided with a hinged dumpin door, ofa dumping door carrier pivota ly mounted upon the bucket, saidcarrierbeing provided with a ledge adapted to support said dumping doorand to be moved into and out of supporting relation therewith v'vhensaidcarrier is swung upon its pivot, said carrier being provided a so with alaterally projecting and apertured arm; a movable latch hook supportedbysaid doorcarrier and detachably lockingsaid carrier lodge in supportingrelation with said dumping'door;

"and a latch hookactuation rod operatively when the bucket descends,thereby enabling pivotal movement of said door carrier.

5. The combination with a bucket provided .with a hinged dumping door,of a shouldered retainer bar rigidly secured to the dumping door andpromoting from one side thereof; a dumping door carrier pivotallymounted upon the bucket, said carrier being provided with a ledgeadapted to engage beneath'the e'nd'of said retainer bar for supportingsaid dumping door and to be moved into'and out of supporting relationtherewith when said door carrier is swun upon its pivot, said carrierbeing provide also with an extension and anapertured lateral projectioncarried by the extension thereof; a latch hook pivotally mounted uponsaid door carrier adjacent said led ge, e

the hook whereof detachably engages shouldered portion of said retainerbar, whereby said carrier ledge is detachably confined beneath saidretainer bar; and a latch hook actuation rod operatively connected withsaid latch hook and arranged end, said knob bein within the aperture ofsaid lateral projection, said rod being movable within said aperture andprovided with a knob at its lower adaptedto engage a stop member when te bucket descends for eflecting longitudinal movement of said rod,thereby disengaging said latch hook from said retainer bar shoulder andenabling pivotal movement of said door carrier for the disengagement ofsaid ledge and the retainer bar.

. In testimony whereof I have hereunto affixed my signature this 19thday of February, 1917.
